Profesyonel doğal vücut geliştirmeciler üzerinde yapılan çalışmalarda farklı antrenman yüklerinin performans üzerindeki olumlu etkileri iyi bilinmesine rağmen, diyafram kas kalınlığının 1RM kuvvetini nasıl etkilendiği belirsizdir. Çalışmanın amacı, diyafram kas kalınlığının profesyonel doğal vücut geliştiricilerde tek tekrar maksimal kuvveti (1RM) ile ilişkisinin incelenmesidir. Çalışmaya ulusal ve uluslararası yarışmalara katılmış aktif spor yapan 15 profesyonel doğal vücut geliştirici dâhil edilmiştir. Deneklerden solunum fonksiyon testleri, 1RM ve diyafram kas kalınlık ölçümleri alınmıştır. Elde edilen verilerin analizleri SPSS 25 istatistik paket programı ile hesaplanmıştır. Çalışmada 1RM değeri ile FVC, FEV1 ve PEFmax parametreleri ile pozitif anlamlı yüksek ilişki olduğu tespit edildi. FEV1/FVC oranı ile negatif düşük düzeyde bir ilişki tespit edildi. 1RM ile dinlenme, ekspirasyon ve inspirasyon evrelerinde diyafram kas kalınlığı ile pozitif orta düzeyde bir ilişki tespit edildi. Sonuç olarak, bu çalışma, diyafram kas kalınlığının vücut geliştirme antrenmanlarında 1RM performansı ile ilişkili olduğunu ortaya koymaktadır. Özellikle, diyafram kasının sadece solunumu destekleyen bir kas olarak değil, aynı zamanda intra-abdominal basıncı optimize ederek güç üretimine katkı sağlayan bir kas olarak da değerlendirilmesi gerektiğini göstermektedir.

Background: The extant research on judo sports has principally concentrated on the physiological effects of training. Conversely, there has been limited attention paid to studies on psychological resilience, self-control, and emotional expression levels. The present study examined the effects of Judo exercises on psychological resilience, self-control, and emotional expression levels in healthy male subjects. Methods: The present study comprised 50 healthy, sedentary male subjects. The subjects were randomly divided into two groups: one group participated in judo training (JT) and the other group served as the control group (CON). The sample sizes for the JT and CON groups were both 25. The JT group underwent judo training, while the CON group maintained their usual lifestyle. The Brief Psychological Resilience Scale, the Multidimensional Brief Self-Control Scale, and the Berkeley Emotion Expression Scale were administered prior to and following the 6-week training period. Results: The study demonstrated that a 6-week judo training regimen exerted a significant effect on the psychological resilience score (e.s. = 1.047, p < 0.001), while no such effect was observed in the Control group (e.s. = 0.0091, p = 0.751). In the context of self-control levels, an effect was observed on the Initiation sub-dimension (e.s. = 1, 739, p < 0.001), yet no effect was found on the Inhibition dimension (e.s. = 0.052, p = 0.892). In the control group, a significant decrease was identified in the Initiation sub-dimension (e.s. = 0, 785, p = 0.001) and Inhibition sub-dimension (e.s. = 1, 861, p < 0.001). The findings indicate that impulse power (e.s. = 0.395) and concealment (e.s. = 0.428) exerted a negligible influence on the emotional expression sub-dimensions. Conversely, psychological resilience (e.s. = 0.886) demonstrated a substantial impact. Conclusions: The judo exercises demonstrated a favorable impact on psychological resilience, self-control, and emotional expression levels in healthy male subjects. The findings of this study may offer significant insights into the impact of judo exercises on psychological resilience, self-control, and emotion expression levels. These findings could serve as a guide for the development of future interventions and program design in the domain of sport psychology.

İncele - MakaleAçık Erişim2025Scopus SJRQ2The effects of different exercise loads in plyometric resistance training on respiratory and hormonal levels in female volleyball players

Background: The present study set out to ascertain the effects of combined exercises, consisting of resistance training and plyometric exercises at varying degrees of intensity, on biochemical and respiratory parameters in female volleyball players. Methods: The research group consisted of 20 professional female volleyball players who participated in national and international volleyball competitions. Participants were randomly divided into two groups: a control group (n = 10) that performed low-intensity exercises at 30%–50% intensity, and an experimental group (n = 10) that followed a high-intensity exercise programme at 60%–80% intensity. Blood samples and spirometric respiratory function values were collected before and after the 8-week exercise program. The biochemical analyses included the assessment of luteinizing hormone (LH), growth hormone (GH), insulin-like growth factor-1 (IGF-1), and total iron binding capacity. Respiratory function was analysed using forced vital capacity (FVC), forced expiratory volume in one second (FEV1), and forced expiratory flow at mid-expiration (FEF). The data were analysed using the SPSS statistical package. Results: The results demonstrated a decline in IGF-1, GH, and total iron-binding capacity levels, and an increase in LH levels, in the biochemical parameters of the control group. Additionally, FVC, FEV1, and FEF values exhibited an increase in the control group. Conversely, the experimental group demonstrated a significant increase in LH, GH, IGF-1, and total iron-binding capacity levels. With regard to respiratory parameters, an increase in FEF values was observed, whilst FVC and FEV1 values decreased. The present findings suggest that high-intensity plyometric resistance exercises have more pronounced effects on biochemical responses, but may trigger different adaptation mechanisms in respiratory capacit. The results of the study showed that there was a difference between the control group’s GH, IGF-1, FVC, and FEV1 data and the experimental group’s GH, IGF-1, FVC, and FEV1 data. Conclusions: In conclusion, plyometric resistance exercises at varying intensities influence both respiratory and biochemical parameters in female volleyball players. Accordingly, well-planned and individualised plyometric resistance training programmes are thought to enhance both the health and athletic performance of athletes.
